A riot or mob violence is a form of civil disorder commonly characterized by a group lashing out in a violent public disturbance against authority, property, or people.
Riots typically involve destruction of property, public or private. The property targeted varies depending on the riot and the inclinations of those involved. Targets can include shops, cars, restaurants, state-owned institutions, and religious buildings.
Political violence is violence which is perpetrated in order to achieve political goals. It can include violence which is used by a state against other states (war), violence which is used by a state against civilians and non-state actors (forced disappearance, psychological warfare, police brutality, targeted killings, torture, ethnic cleansing, or genocide), and violence which is used by violent non-state actors against states and civilians (kidnappings, assassinations, terrorist attacks, torture, psychological and/or guerrilla warfare). It can also describe politically motivated violence which is used by violent non-state actors against a state (rebellion, rioting, treason, or coup d'état) or it can describe violence which is used against other non-state actors and/or civilians. Non-action on the part of a government can also be characterized as a form of political violence, such as refusing to alleviate famine or otherwise denying resources to politically identifiable groups within their territory.
Due to the imbalances of power which exist between state and non-state actors, political violence often takes the form of asymmetric warfare where neither side is able to directly assault the other, instead relying on tactics such as guerrilla warfare and terrorism. It can often include attacks on civilian or otherwise non-combatant targets. People may be collectively targeted based on the perception that they are part of a social, ethnic, religious, or political group; or selectively, targeting specific individuals for actions that are perceived as challenging someone or aiding an opponent.
